The document discusses an application called Idea Street created by the United Kingdom's Department of Work and Pensions to increase employee collaboration and sharing of new project ideas using gamification. Employees were motivated to use the application and contribute ideas due to receiving quick feedback, badges for their contributions, and rising on the leaderboard. Within 18 months of using Idea Street, about 4,000 employees generated 1,400 new project ideas, with 63 projects being implemented by the Department.
